I'm not sure how many people get stuttering with this game but there is one solution which works for me in this and Doom 3.
In the same folder as your config file make a file called "autoexec.cfg" and open with a text editor and input: seta com_fixedtic "1"
I played Doom 3 several times over the years before I found that setting. This could help people new to the game(s).
As a side-note there is also a similar fix for quake 1 that i am currently using with dark places which is: set sys_ticrate 0.0166667
I'm running at 60hz
com_fixedtic is always on. You used to be able to disable it to, but Id removed that ability long time ago in patch 1.2 I believe.
com_fixedTic [-1,0,1] - If set to 0 (the default) Doom 3's ticrate is capped at 60FPS, meaning the game framerate cannot exceed this, except when running a timedemo. If you want to remove this cap, set com_fixedTic to -1. Setting it to 1 removes the cap, but causes the game physics to go out of sync. Removing the FPS cap doesn't necessarily improve performance, and can lead to more variable framerates. Note that com_fixedTic -1 doesn't work as of the latest patch.
